System Information
Windows 7 64bits NVidia GTX 580

Blender Version
Broken: Blender 2.74 RC4
Long standing bugs, at least since 2.72, probably earlier

Short description of error

Deleting end segment of curve leaves loose vertex
and
If the bevel object is in a different from the curve path scene it won't automatically update beveled geometry

Exact steps for others to reproduce the error

Deleting end segment of curve leaves loose vertex:

Add a curve circle
Enter edit mode
Delete one random segment
Now delete one of the new end segments

Loose vertex is left behind

If the bevel object is in a different from the curve path scene it won't automatically update beveled geometry

Default new scene
Add new bezier curve
Create new scene in same blend file
Add a new bezier curve
Add bezier curve from previous scene as bevel object
Go back to first scene
Enter edit mode in first bezier
Introduce some random transformations (move some vertex around)
Exit edit mode and return to second scene where curve is used as bevel object
Second curve's bevel geometry is not updated, one must manually enter edit mode to force update.

A few things:

Please always open multiple reports if you have multiple bugs. Could you open another report for the second bug so we can focus on the first bug here?
For the first report: I'm not sure what you mean, but please always attach a .blend and give exact steps to reproduce it based on it so we can reproduce the issue as easy as possible

My apologies, I'll clean this up as soon as I get back to my computer, I'll open a new bug report and post example files.
This seems very straightforward to recreate though.

On the Blender default scene go to the 3d view
shift +a add>curve >bezier circle
tab to enter into edit mode
select any two consecutive vertex
x>delete segment
now select one of the remaining end vertex and a consecutive one so that one of the end segments is selected
x>delete segment
now the curve segment is gone, but the trailing end vertex was left behind floating and not attached to the rest of the curve
One would expect that vertex to be gone

Ok here is a demo file: bezier_loosevertex.blend
If you go to curve A and delete the already preselected segment by going x>delete segment you end up with the result on curve B with a floating loose vertex where the end of the curve was.
Curve C would be the expected behavior

I’m sorry, but I see no bug here, if you delete a segment, you do not delete a control point… Thanks for the report anyway.
